SPECIFICATION forming part of' Letters Patent No. 248,039, dated October 11, 1881.

Application filed April 22, 1881. (No model.) I l 1 0 all whom it may concern:

Be it known that I, GEORGE HAYNER, a citizen of the United States, residing in the village of Lansin gburg, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Grates for Stoves, Heaters, and Furnaces. of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in coal-supporting grates which can be vibrated horizontally to sift out ashes, and of which a part can be separately moved laterally to open aspace through which cinders,cl inkers, stones, and unburned coal can be dumped.

The general object of my invention is to produce a very simple, cheap, durable, effective, and easily-operated stove, heater, or furnace grate which can be vibrated about a center or centers of 'motion located so as to give long to-aud-fro movements in a horizontal plane to the whole middle portion of the coal-supporting surface of the grate and to nearly all the outer portion thereof, for thoroughly sifting out ashes from the burning coal, and through and across which grate a space wider at one end than at the other can be easily opened and closed to permit the handy discharge of cinders, clinkers, and unburned coal. 1

In the aforesaid drawings, Figure 1 is a plan of one of my improved. grates and its ring-like support. Fig. 2 is a plan of the same, showing one half-section of the grate turned to one side, so as to open a space wider at one end than at the other through and across the grate. Fig. 3 is a plan of the same grate and its support with the two halves of the grate secured together and turned to one side as whenibein g vibrated to sift out ashes. Fig. 4 is a front elevation of the same grate and its supportin the position represented in Fig. 1. Fig. 5 is an elevation of the inner edge of one half of the grate and a section of its support at about. the line 2 z in Fig. 1. Fig. 6 is a plan of the grate-support, and Fig. 7 a plan of one of the sections of the grate shown in Figs. 1,2,3, and 4. Figs. 8' and 10 are plans, and Figs. 9 and 11 sectional elevations, of broken-01f portions of two grates and their supports, show in g modifications in the pivoting of the grates. Fig. l2shows a side and edge of a shaker-bar by which the two pivoted halves of the grate horizontal, or nearly horizontal, in a stove,

heater, or furnace.

Circular grates in stoves and heaters are commonly so pivoted or mounted that the whole grate can be vibrated in, or nearly in, a horizontal plane about a center of motion located at or very near the center of the coalsupporting area of the grate, and consequently the middle portion of the grate and the coal and ashes on that portion are only slightly agitated by the horizontal vibrations of the grate about its center of area. To avoid that defect and to mount the grate so as to secure extensive to-and-fro horizontal motion to the whole central and middle portion of the grate and to nearly all its outer portion by vibrating the whole grate about a center or centers of motion, I hinge or pivot the grate A A to its support B, or any equivalent therefor, at a point or adjacent points at or near the outer edge of the grate, so that the whole grate can be vibrated in a horizontal, or nearly horizontal, plane upon the support B or its equivalent, and about the said hinge or pivot point or points at one side edge only of the grate as a center or centers of motion.

To provide means for easily opening and closing a space wider at one end than at the other through and across the grate when supporting burning coal, to permit-the convenient removal of cinders and clinkers, I make the grate in two flat half-sections, A A, and pivot or hinge one end part, 0, only of one section to the adjacent end part of the other section, or to the grate-support B or its equivalent, so that the said hinged or pivoted half-section can be easily turned horizontally upon its support and about its hinge or pivot as a center of motion away from and toward the other half-section, substantially as indicated in Fig. 2, and thereby open and close a tapering space, Y, through and across the grate.

To provide facilities for quickly dumping a large mass of coal and cinders through the grate, I hinge or pivot the two end parts, 0 c,

of the two half-sections A A to the support B I or its equivalent, so that both half-sections can be turned horizontally upon their support and about their respective hinges or pivots away from or toward each other, and thereby open or close centrally across the grate a wide space. (Indicated in Fig. 2 by the positions of the inner edges of the part A in full lines and the part A in dotted lines.)

I11 order that the two halves A A ot'the grate may be vibrated together horizontally as one complete grate, with an extensive to-and-fro movement of the central portion thereof, I so hinge or pivot to the support 13 or its equivalent each of the two halves at or near one end only oftheir line ofdivision that the two halves can be vibrated together horizontally upon their support and about their hinges or pivots part way across the position of the line of division ofthe two halves when they are placed as shown in Figs. 1 and 4, for supporting coal in the firepot over the grate. In Fig. 3 the two halves A A are shown together in full lines at one end of their vibrating movement and in dotted lines at the other end thereof.

In Figs. 1 and 4 the broken lines' aindicate about the position of the lower inner edge of the fire-pot, which must be supported over and above the grate in the stove, heater, or furnace in which the grate shall be used.

To provide convenient means for temporarily securingand vibrating together the two hinged or pivoted halves A A as one whole grate, I form the swinging end parts of the two halves each with a socket, d, Figs. 1, 2, 4, and provide a shaker bar or handle, E, Fig. 12, formed at one end with two lugs, ff, adapted to fit into the sockets d d of the two halves of the grate when they are close together, as represented in Fig. 3, so that by means of the handle E a person can easily and quickly secure and vibrate together the two halves A A as one whole grate.

The sockets d d can be of any suitable shape, and either horizontal, inclined, or vertical, as indicated by Figs. 1, 2, 3, and 4, and the corresponding lugs ff can project endwise or laterally from the handle E, as shown by full and dotted lines in Fig. 12. As an equivalent construction, the sockets d d can be in one end part of the handle E and the lugsff on the swinging end parts of the two halves of the grate.

To facilitate the placing of each or both of the hinged or pivoted half-sections of the grate in the proper position on their supportfor holding burning coal in a fire-pot over the grate, andto preventaccidentaldisplacementofeither section of the grate from that position, and yet permit easy lateral vibrative movement of either half or both sections of the grate, and to increase the agitation of coal in the fire-pot by the vibratory motion of the whole grate, I form rounded or obtuse projections g 9, Figs.

4 and 6, on the upper surface of the support and in the path of the movements of the swinging end parts of the two grate-sections, and make in the under surface of the latter corresponding recesses h h, Fig. 4, all so arranged that the projections shall be in the recesses when the two halves of the grate shall be in the position represented in Figs. 1 and 4. For the same purpose the projectionsg gcan be on the under side of the grate-sections and the recesses h h in the upper surface of the grate.- support.

In the grate represented in part by Figs. 10 and 11 the section A is hinged to the section A and the latter is pivoted to the support B, all by a stem, 2', fast on section A and extending through a perforation in an ear,j, on section A, and also through a socket, k, Fig. 11, in the support. In the grate partly shown in Figs. 8 and 9 the two sections A A are pivoted concentrically to the support 13 by two segmental stems, ll, one fast on each of the sections, and both extending side by side through one and the same circular perforation m in the support.

To secure agreater extentof horizontal movementto the hinged or pivoted side portion,n a, of the grate than can be had when the grate, either in one piece or in two halves secured together, shall be hinged or pivoted at one and the same point or center of motion, as shown in Figs. 8 and 10, I loosely hinge or pivot the grate A A, whether made in one piece or two half-sections, to the support B, or its equivalent, at two points at or near one side edge of the grate and a little distance apart, as shown in Figs. 1, 2, and 3, by having two pivot-stems, o 0, fast on the grate, or one on each half-section, and extending into or through enlarged or elongated sockets or perforations p 12, Fig. 6, in the support, so that in the horizontal vibrations ot'the wholegrateorofthetwohalf-sections secured together the pivot-stemso 0 shall move in opposite directions to and fro within and lengthwise of their elongated sockets p p, as indicated by full and dotted lines in Fig. 3, and thereby secure a sufiicient or important de ree of vibratory movement to the hinged or pivoted outer side portion of the grate.

To prevent either of the two half-sections A A from sliding along the other in the direction of their dividing-line when the two sections are loosely hinged or pivoted to the support B,or its equivalent, at separate points,as represented in Fig. l, and the two sections are connected together and vibrated horizontally, as indicated in Fig. 3, by the shaker E or other suitable means, and to thus securely cause the two sections to vibrate together, substantially the same as if they were cast together in one and the same piece, I form opposite parts of the inner edges of the two sections, one with a lug, q, Fig. 2, and the other with a corresponding notch, r, into which the lug fits when the two sections are close together, as represented in Figs. 1 and 3.

To properly secure each pivot-stem 00, Figs. 3 and 5, l 1, Figs. 8 and 9, and 2', Figs. 10 and 11, in its socket, and also permit easy removal and insertion of each pivot-stem when fast on a grate-section, I commonly form the end of each pivot-stem with alateral projection, 8, Figs. 5, 7, 9, 11, adapted to be passed through the pivot-socket and to extend beyond its edge, as indicated in the latter figures. 7

In carrying out this invention each pivotstem, 0 l l t, can be fast on the support B or its equivalent, and each socket or perforation, p p m k, in a part of the grate; or each pivot-stem can be a separate piece, fitting in sockets in a grate-section and its support, in-

.stead of having the pivot-stems fast on the grate-sections and the pivot-sockets in the grate-support, as shown in the drawings, and as is commonly preferred.

What I claim as my invention is- 1. The combination, with the support, of the grate hinged or pivoted at one side only of the outer edge of the grate, substantially as described, whereby the grate is adapted to be vibrated horizontally on thesupport about a center of motion at the edge of the grate, as set forth.

2. The combination, with the support, of a grate composed of two half-sections, A A, of which one is hinged or pivoted at one end part only, and thereby adapted to be turned horizontally on the support away from and toward the other half-section about a center of motion at or near one edge of the grate,substantially as described.

3. The combination, with the support, of a grate composed of two half-sections, each of which is hinged or pivoted at one end part only, substantially as described, whereby the two sections are adapted to be turned horizontally on the support either away from ortoward each other, as set forth.

4. The combination, with the support, of a grate composed of two half-sections, each hinged or pivoted ator near one end only of their line of division, substantially as described,

pivoted at or near one end only of their line of division, of the detachable shaking-handle engaging with and securing together the swingingend parts of the two sections, substantially as described.

6. The combination, with the support and the grate composed of two half-sections hinged orpivoted at or near one end only of their division line, of the projections g g and recesses h h, arranged respectively in and upon the support and the two sections of the grate, as set forth.

7. The combination, with the support and grate, of the two pivots 0 0, somewhat apart from each other and at one side only of the outer edge of the grate, and the elongated sockets p p, in which the pivots move to and fro in the lengthwise directions of the sockets as the grate is vibrated horizontally on the support, substantially as described.

8. The combination, with the support and the two grate-sections loosely pivoted to the support at two separate points near one end only of their line of division, substantially as described, of the lug q and opposite notch, V, respectively in and upon the inner edges of the two grate-sections, substantially as set forth.

In testimony whereof Ihereunto set my hand, in the presence of two subscribing witnesses, this 20th day of April, 1881.
